COOLING TANK.

Application led July 30,

This invention relates to improvements in cooling tanks, particularly adapted for'l in connection with refrigerating apparatus and the like.

An object of this invention is to provide perature in less operating time for the compressing unit than is possible in the devices now used in ordinary practice.

A further object of this invention is to provide a tank construction having a main body portion made of a single section of cast metal such as cast bronze or the like, the cooling area and means for facilitating the ice cube freezing being increased by suitably connecting to the main body portion of the tank, tu-

bular sections in open communication therewith.

Further objects of this invention will ap pear in the following detailed description of this device and as disclosed in the single sheet of drawings which is herewith made a part of this application:

In the drawings,

Fig. 1 illustrates an end elevational view of the cooling tank in assembled relationship showing a section broken away in order to disclose the sealing means between the lid or cap and the main body portion of the tank.

Fig. 2 represents a side elevational view of Fig. 1.

Fig. 3'illustrates a plan view of Fig. 2.

Numeral 1 designates the main body portion of the cooling tank which may be made of any suitable'material such as cast bronze formed into any desirable shape by casting for the purpose set forth. The body' portion '1 of the tank is adapted `to have outwardly extending therefrom along its upper edge,

`'and integrally therewith, a flange portion 2 which is adapted to be brought into sealed relationship with a cap or lid section 3 by.

means of machine bolts 4 or otherwise. In

order to effectively seal the lid and main body 1926. Serial No. 126,059.

line these elements bein connected in any suitable. manner to the re rigerating apparatus.

In order to increase the cooling area and to facilitate fthe ice cube freezing, a plurality of tubes are brought into open communication with the main body portion 1 of the tank.`

e These tubes or coils are designated by numeral 6 and arev preferablymade from copper tubing hermetically sealed or suitably connected to the main body tank portion 1, through openings@ therein, which may be drilled for receiving'the ends of the coils 6. The coils 6 are so arranged in relation to each other as to form suitable receptacles for receiving ice pans 7, the ice pans 7 are supported by means of suitable extensions 8 between the tubular members 6. Absorption coils or tubes 10 are adapted to extend from the sides of the main body portion 1 preferably from a point near `the bottom thereof and through openings 11 therein, these openings 11 mayT be drilled so as to receive the free ends of thepcoils 10, the ends of the coils 10 being hermetically sealed in any suitable manner to the main body portion 1 through openings 11. y

.Itis preferred in this invention to arrange the cooling tubes and the absorption coils in the-relationship disclosed in the drawing, but it is understood that the absorption coils may be located at anv desired angle to the main body portion without affecting the merits of this invention, likewise variations and substitutions may be made for the cooling tubes 6 disclosed herewith within the scopevof this invention.

In order to increase the absorption area a shield `or cover 11 for the pans 7 may be located between the cooling tubes 6 and 'surroundingvthe pans, thereby forming a shelf closed at the sides for receiving the pans.,V

This invention provides a cooling tank having` an efficiency ordinarily double that of the more common types now in use. The location of the side absorption coils in this invention functions to make it possible to obtain a much lower temperature in less operating time for the compression unit. From the fact that the tank is made from practically a single casting and the lid having in combination therewith absorption tubes, cooling tubes, and pans with their supports, it is apparent that the cost of production is greatly reduced, thereby over the expense of manufacturing a cooling tank of the ordinary type. The tank 1s made from a minimum number of elements in a very simple manner thereby reducing greatly the amount of labor necessary in the manufacture.

What claim is:

A cooling tank consisting of a main body portion of suitable metal, the portion having an opening in the top, a lid or cap for the opening, the lid being brought into sealed relationship with the main body portion, absorption coils extending from the sides of the main body portion, the ends of the coils being in o en communication with the main body portlon of the tank and hermetically sealed thereto, cooling tubes extending from the Madere main body portion and in open communication therewith, the ends of the tube'being hermetically sealed to the main body portion, the cooling tubes being arranged to receive cooling pans' therebetween, the pans having suitable supports extending between the tubes, means for increasing the absorption area consisting of'a shield made of suitable absorption material adapted to coverlthe ice pans between the cooling tubes, thereby forming a closed shelf for the pans.

In testimony whereof I aiiix my signature.
